The study of productivity and manufacturability of pea varieties, both existing and removed from zoning, was carried out. The tasks of the paper included analysis of a sample of pea varieties in terms of yield, the main features of productivity - the number of productive and unproductive nodes, seeds and beans per plant, their variability; assessment of the influence of the genotype, growing conditions and the interaction of these factors in the formation of signs of productivity and manufacturability; identifying the relationship between the main features of productivity, productivity and manufacturability in order to determine the vectors for further breeding work with the crop. In terms of yield, the effectiveness of the crop variety change was revealed. In terms of productivity elements, the Kan variety had the maximum indicators, which allows us to consider it as a source in terms of the number of beans and seeds per plant. A significant influence of the genotype on resistance to lodging of 53.34% was revealed, with the influence of the conditions of the year of 0.77%, the interaction of factors of 45.87%, and the average positive dependence of yield with resistance to lodging of plants in varieties with a mustachioed leaf type (ґ=0.63±0.19), therefore, the introduction in the breeding process of high-tech varieties can help increase yields. In different years, the yield was influenced by different signs of productivity (2019 - the number of beans and seeds, 2020 - the number of grains of the bean, 2021 - the number of productive nodes and the grain content of the bean), with a strong mutual contingency (r = 0.76...0.93). Due to the impossibility of isolating any one trait that affects the yield, breeding work should be carried out in a comprehensive manner and be aimed at the development of all elements of productivity.

The main legume crop, pea, is characterised by various morphotypes: leafy, whiskered, chameleon and other morphotypes. These morphotypes are the result of both selection work and spontaneous mutations. The relevance of the research topic is the effect of various factors, including seed treatment, on the different morphotypes. Six varieties and breeding lines of pea sown by Krasnoyarsk Research Institute of Agriculture were taken for the study: leafy Radomir, Kemchug; with the moustached leaf D-94, Ruslan; and having longitudinal heterophyllia L-19, M-6. This work aims to determine the responsiveness and variability of germination and germination energy, as well as seedling length, recorded during these periods, of different morphotypes of pea varieties and breeding lines to seed treatment with a growth stimulant. The experiment was set up in three replications with the growth stimulant treatment sodium humate and three repetitions of the control variant without remedy. Measurements of seedling length, germination energy and germination were carried out on the 4th and 8th day, respectively. The research revealed that the treatment of pea seeds increased the germination energy by 2,28% and reduced its variation by 0,55%. Chameleon morphotype samples are more responsive to treatment. The variability of the coefficient of variation of the germination energy of pea plants of different morphotypes with and without treatment is less than 10%. Stimulant treatment increases the length of seedlings by 6.34% but does not affect the morphotypes separately. The increase in size at treatment is individual for each sample. The variability of variation in the length of seedlings of control and treated examples is insignificant and unique for each model. But this variability in size decreases throughout the experiment: on the 4th day from 1.63 to 1.36, on the 8th day from 0.98 to 0.95%. In determining the germination rate, it was found that the treatment of pea seeds with a growth stimulant increases it by 3.78%. The growth gain is an individual response of each specimen and is weakly dependent on the morphotype.

The research was conducted in 2018-2020 in the forest-steppe zone of the Krasnoyarsk Territory. The soil of the site is ordinary heavy loamy chernozem, with a low content of nitrate nitrogen (4 ... 6 mg/kg of soil), an average content of mobile phosphorus (19.7 mg/100 g) and a high content of exchangeable potassium (12.6 mg/100 g). Weather conditions during the study period were different in terms of heat and moisture availability of the growing season: 2018-medium arid (SCC 0.60), 2019-insufficiently humidified (SCC 0.89), 2020-sufficiently humidified (SCC 1.32). The object of the study was 9 samples of field peas, the standard is a zoned variety of seed peas, grain-bearing direction, Radomir. The aim of the research was a comparative assessment of the adaptability of the mass of 1000 seeds of collection samples of field peas. The tasks were set to determine the indicators of adaptability of samples by the weight of 1000 seeds: ecological plasticity (bi), homeostaticity( Nom), coefficient of adaptivity (KA), coefficient of multicativity (KM), stability indicator (PUSS); by ranking the obtained indicators, to determine the most adaptive samples of field peas by the mass of 1000 seeds in the conditions of the East Siberian forest-steppe; to determine the variability of the studied indicator by years and to identify correlations of the mass of 1000 seeds with the indicators of adaptability. As a result of the study, it was revealed that in most cases, the adaptive abilities of field peas were higher than those of the standard-field peas, which allows us to recommend Pisum arvense L. to attract Pisum sativum L. to hybridization during breeding. in order to increase the adaptability of the indicator, the weight of 1000 seeds. It was found that Tabyz, Pleiofilia tupe and K-9031 were the most adaptive in terms of the mass of 1000 seeds in the conditions of Eastern Siberia from the studied samples of seed peas. The variability of the trait over the years was insignificant – less than 10%, and only in two variants – Tabyz and K-4375 average-from 10% to 20%. A strong dependence of the mass of 1000 seeds with the following indicators was revealed: Hom homeostaticity (r=0.88±0.17), KA adaptivity coefficient (r = 1.00 ± 0.00) and the PUSS stability level indicator (r = 0.88 ± 0.17); the average with a regression coefficient bi (r = 0.31 ± 0.34) and a weak negative with a multicativity coefficient KM (r = -0.11 ± 0.35).

The studies were carried out in the conditions of the Krasnoyarsk forest-steppe on the basis of the Krasnoyarsk Research Institute of Agriculture. The weather conditions of the years of the study differed from each other: 2018 - very dry Hydrothermic Coefficient (HC) 0.60; 2019 - arid HC 0.89; 2020 - moderately humidified HC 1.32. The soil of the plot is ordinary heavy loamy chernozem with an acidity of the soil solution of 6.8 and humus content of 7.8 (according to Tyurin). The researches were carried out in accordance with the guidelines for the study of the collection of the world’s genetic resources of cereal legumes. For the study, 9 samples of peas of different morphotypes were taken. The proportions of the influence of genotype and year conditions on the characteristics of the productivity of the samples were determined - the number of unproductive and productive joints, the number of beans and seeds per plant, and the length of plants. The climatic conditions of the year of cultivation had the greatest influence on the main characteristics of productivity, such as the number of beans per plant, the number of seeds per plant, and the number of productive joints. In terms of the number of beans and seeds per plant, 75% was attributed to the influence of the conditions of the year and 45% to the influence of the variety and the interaction of factors, variety x year. The length of the plants was significantly influenced by the year of cultivation - 66%, the influence of the genotype was estimated at 24%, the interaction of factors at 10%. The factor of the year had a minimal effect on the number of unproductive joints - 19%, the influence of the variety was 80%.
